public class ROM
- extends SynchronousFixTransformer
Produce an output token on each firing with a FixPoint value that is
equal to the concatenation of the input bits from each input channel.
The ordering of channels determines the order of the concatenation; inputs
from later channels are appended to the end. The input can have any scalar
type.

ROM
public ROM(CompositeEntity container,
java.lang.String name)
throws NameDuplicationException,
IllegalActionException
- Construct an actor with the given container and name.
- Parameters:
container
- The container.name
- The name of this actor.
- Throws:

throws IllegalActionException
- Override the base class to determine which function is being
specified.
- Overrides:
attributeChanged
in class SynchronousFixTransformer

attribute
- The attribute that changed.
- Throws:
IllegalActionException
IllegalActionException

port does not depend on the output in a firing.
- Specified by:
preinitialize
in interface Initializable
- Overrides:
preinitialize
in class SynchronousFixTransformer
- Throws:
IllegalActionException
